UPDATE: T-Mobile suspends Sidekick trade-ins?

We're getting reports that T-Mobile has temporarily halted their trade-in program where they were offering current Sidekick owners a hundred bucks off the new Sidekick II
in exchange for turning in their old one, and have supposedly even disconnected the toll-free number they'd given people to call (we tried a few times and just got busy signals). Not sure if the problem is simply overwhelming demand or not, but at least one tipster says that T-Mobile had some sort of SNAFU with their billing system and are going to try and get things going again in a few days.
